The document describes the CY2292 three-PLL general-purpose EPROM programmable clock generator, including three integrated phase-locked loops, EPROM programmability, low skew, low jitter, high-accuracy outputs, power management options, frequency selection options, smooth slewing, configurable 3.3V or 5V operation, etc.
The CY2292 is a third-generation family of clock generators designed for PC motherboard and synchronous system applications. It features three integrated phase-locked loops (SPLL, CPLL, UPLL) that allow the generation of up to three custom frequencies from external sources with low skew and jitter.
| Integrated Phase-Locked Loops | Three integrated phase-locked loops |
|---|---|
| Supply Voltage (5V operation) | 4.5 V to 5.5 V |
| Supply Voltage (3.3V operation) | 3.0 V to 3.6 V |
| Operating Temperature (Commercial) | 0 °C to +70 °C |
| Max. Load Capacitance (5V) | 25 pF |
| Max. Load Capacitance (3.3V) | 15 pF |
The output frequency range is 76.923 kHz to 100 MHz at 5V and 76.923 kHz to 80 MHz at 3.3V.
No, the standard CY2292 is factory-programmable; only the CY2292F variant supports field programming.
